AtheneNoctua, it would surely be seen by the relatives of the 290 innocents who died in the Iranian airliner as the height of insenstivity to give a hero's welcome to the crew who made such a grave and catastrophic mistake?
ilovemydog, being able to visit your terminally ill husband in prison is not the same as having him at home with you, surely.
Before Megrahi, 30 prisoners had applied for compassionate release since the legislation was implemented to allow it. 23 of them were granted. The 7 that were not granted failed because the medical evidence did not support it. Given that the legislation apparently does not allow for account to be taken of the nature or gravity of the crime, exactly what grounds would Kenny MacAskill have had for refusing a competent application under this legislation (competent in the sense that the medical evidence stated that Megrahi is terminally ill and is expected to die within 3 months). As far as I can see, refusing the application would have required MacAskill to make a political, not a quasi-judicial, decision. That would have been wrong.
Megrahi could not have received adequate care in his last stages in prison (and to suggest that he should not have received proper care would, of course, be beneath contempt) and caring for him elsewhere would have had a massive impact on other people being cared for at the same location because of the security requirements.
If we are going to be better than "murdering cowards", we are required to behave better than they do. Showing compassion to one who, if guilty, showed none to his victims is a way that we do this.
Besides, there is doubt in some quarters as to the safety of Megrahi's original conviction - and this is not solely the preserve of crackpot conspiracy theorists. Among those who doubt Megrahi's guilt are Jim Swire, father of a 24 year old daughter who died at Lockerbie, and Professor Robert Black, a legal academic who was instrumental in setting up the Scottish Court in the Netherlands where Megrahi was tried. Black has written extensively and eloquently on the subject. Read his blog.
